Adding those two lines (with . instead of ->) does fix the issue for me,
thanks.

That particular patch changed things because the original memcpy in
new_pts_mount() did this:
memcpy(&fsi->mount_opts, opts, sizeof(opts));
where opts was a pointer, not a structure. So only the first few bytes
of the blank opts actually got copied over. The patch moved this memcpy
to devpts_get_sb() and in the process fixed the sizeof error.
